FAQs
Frequently asked questions

The usual causes are dirty or cracked flame rod, failed uv scanner, poor earth on the flame sensing circuit, incorrect air/fuel ratio. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?

Can I keep using the system in the meantime?
No — isolate the plant and call 069 268 0988. Running it in this condition risks further damage or an unsafe situation.
